Eight of the injured firefighters were released Saturday after being treated overnight. The other three did not require hospital visits, said Jerry Sharp, a CalFire spokesman.

"Everyone's OK, thankfully," he said.

The fire, located about 160 miles north of San Francisco, is 30% contained and has consumed nearly 7,100 acres. Several areas were evacuated, but hundreds of people were allowed to return to their homes Saturday.

At least four other blazes are still burning in the state and have consumed more than 134,000 acres. More than 7,500 local, state and federal fire crews have been fighting the blazes, most of which were caused by lightning earlier this week.
